Abstract

PURPOSE:To prevent the burning of a resistor in a circuit and the heating of a motor by controlling the exciting current of the motor when the interval of exciting phase switching pulses becomes longer than the predetermined time. CONSTITUTION:A time circuit RM generates, when a phase switching pulse ECP does not arise even after the lapse of a predetermined period, an output ''1''. This output is applied through a logic OR circuit OR to a current limiter LM to limit the current to a motor driving amplifier. The output of the timer circuit TM is inverted, the inverted output is applied to an AND circuit, and the output signal from a distributor DSB is also applied to the AND circuit, which produces an output to a motor driving amplifier. Accordingly, when an error operating signal ER arises, a motor driving current is interrupted.
